Bluetooth Data Format of an ORION XS 50 (Extra Manufacturer Data)

Modifications

Bonjour,

I’m trying to retrieve information from an Orion XS 50 via BLE with an WaveShare ESP32 S3 touch 5 inches— specifically, the output current in amps. In the “Extra manufacturer data” document, within the table for DC/DC devices, this value isn’t listed — only the input or output voltage. Do you know if an updated version of this document exists (I haven’t been able to find one), or if you happen to know the data format used by the Orion?
At the moment, thanks to this document, I’m able to retrieve data from a SmartBMV and a SmartSolar, but not from an Orion.

Merci !

Hi,

The OrionXS has a different Instant Readout record than the previous SmartOrions. The record definition for the OrionXS is:

|Start bit|Nr of bits|Meaning            |Units |Range              |NA value|
|---------|----------|-------------------|------|-------------------|--------|
|       0 |        8 | Device state      |      |          0 .. 0xFF|        |
|       8 |        8 | Error code        |      |          0 .. 0xFE|        |
|      16 |       16 | Output voltage    |0.01 V|-327.68 .. 327.66 V|  0x7FFF|
|      32 |       16 | Output current    | 0.1 A|-3276.8 .. 3276.6 A|  0x7FFF|
|      48 |       16 | Input voltage     |0.01 V|      0 .. 655.34 V|  0xFFFF|
|      64 |       16 | Input current     | 0.1 A|      0 .. 6553.4 A|  0xFFFF|
|      80 |       32 | Device Off reason |      |     0 .. 429496728|        |
|     112 |       16 | Unused            |      |                   |        |

Bonjour,

Thank you, Thiemo, for your quick and precise reply.
In the meantime, I looked more carefully through the Victron Community forum and found the same table you mentioned (discussion “Orion XS 12V/12V-50A Bluetooth Advertising Data” with William Christian Bonner / WCBonner and Bruno / bmedici — https://community.victronenergy.com/t/orion-xs-12v-12v-50a-bluetooth-advertising-data/2183/7).
So, Smart Orion and Orion XS are indeed different!
Now I understand why the two documents — “Extra Manufacturer Data” and your table — provide completely different information.
I also found a similar table for the AC chargers. I’ll try to see what data I can retrieve from my IP22.

Best Regards.

Bonjour again,

Can a Victron device broadcast two different product codes (“Record Type”) in its Bluetooth advertising data?

I’m using this code to identify each device type and select the proper data decoding method. However, when I ran a small program to scan the Record Types from the four devices we have onboard, I got the following results:

  • SmartSolar: 0x01 or 0x13

  • BMV-712: 0x02 or 0xD5

  • Orion XS 50A: 0x0F or 0x7F

  • IP22: 0x8D

Is it normal for a device to sometimes send a code different from its “official” Record Type (e.g., 0x01, 0x02, 0x0F)?
Occasionally, the IP22 charger even returns a Record Type of 0x00, which appears to be a test record containing almost all zero data fields:

Hi,

Normally a device only sends 1 type of instant readout record. What is probably happening here is that there are devices configured for VE.Smart networking. This will lead to completely different types of messages besides the product announcement / instant readout messages. So for Instant Readout it is important that the 3th byte is 0x10. Any other value there means it is not a product announcement message and thus does not contain instant readout data.

The data above also does not really look like instant readout data so no idea what is going on there.

Thank you Thiemo,

It’s still stuck!

I’m working on a C++ application to retrieve data from 4 Victron devices. It works for the BMV712 and the SmartSolar, however I can’t get the basic informations from the IP22 charger and the Orion XS.

For the IP22 and Orion XS, I can’t even get type 0x10 records, nor their Product Code (0x08, 0x0F) or the first byte of the encryption key.

To help myself, I wrote a small program just to study the basic informations, before going further to retrieve the “real” data (Voltage, Amperage…)

Here is the small program and the trace it produces.
The method is the same for all 4 devices, but it only works for 2 of them.
Am I making a mistake? Is the encoding used by each device different?

Thank you for your help.

Additional information:

For the Orion and IP22, in the traces, at best when the Beacon Type equals 0x10, the subsequent data is always zero - these are only test records.

Another observation: It seems that the data reception rate from the IP22 is slower than the other 3 devices. I receive data much less frequently.

Hi @VANTHUAN

I believe the problem is in the toCharArray function. I think this stops on the first \0 character and for the OrionXS and the IP22, the first byte after the 0x10 byte is 0x00. If it then stops copying, the remainder will be empty.

Perhaps you can try to copy the string using:
memcpy(manCharBuf, manData.c_str(), manDataSize + 1);

And I would strongly suggest to add a check that the beaconType is 0x10. This will save a lot of logging.

With kind regards,
Thiemo van Engelen

Bonjour,

So that’s it then! :grinning_face: I can’t wait to try it with a new code. Unfortunately, I’ll be away for a week, but once I’m back, I’ll test it as soon as possible and share my feedback here.

In this small program, it’s true that I’m not filtering on code 0x10 — that’s on purpose, to see everything that’s being received. But it’s only a test program to try to understand why I’m not getting any data from the Orion and the IP22. Of course, in the final program, this filtering will be included.

Thank you for this prompt reply.

Best regards

Bonjour,

I modified the code like that:

uint8_t manCharBuf[32];

memcpy(manCharBuf, manData.c_str(), manDataSize);

and indeed it now works very well. The data retrieval from the Orion XS and the IP22 is functioning correctly.

Thank you for this valuable help. I was really stuck. :folded_hands:

The only remaining issue is that I am able to receive data from the Orion at a fairly high rate, about once per second, i.e., like the BMV, whereas the reception from the SmartSolar is slower, about every 3 seconds, which is still acceptable.

But the major problem comes from the IP22, from which I only receive data every 15 to 20 seconds.

Is it normal for this device to send its data so slowly?

Best Regards.

Hi,

All devices will advertise (send out BLE packets) at approx. the same rate. The data in the packets is updated at a rate of once per second on all devices. So when you receive less packets or updates, then this is something in the Arduino code. Or perhaps it is a range / RF problem.

Bonjour Thiemo,

Thank you for this quick and precise answer.

The code is the same (same logic) for the IP22 and for the other three devices, which are received correctly.

So for now, I am ruling out a software issue. Furthermore, all the devices are in the same location, within about 20 cm of each other. When I run tests, I am about 3-4 meters away at most from the devices, in a low-interference environment (polyester-wood boat). I will therefore conduct new tests by moving very close to the devices to eliminate any issues related to transmission power or interference.

Best Regards,

Bonjour,

This is indeed a distance-related issue.

So I conducted a test by moving the ESP32 closer to/farther from/closer again to the devices (Smart Solar, IP22, Orion) which are grouped together. They are within 3.5 meters. When brought closer, the reception frequency for the IP22 becomes comparable to the other devices. Therefore, it seems that the IP22’s signal strength is lower than the others. I will add a trace to measure the RSSI of the devices for comparison.

Is there a way to increase the Bluetooth transmission strength of the IP22, or how can I detect if it has a problem? Or could a future firmware update improve this? The devices are currently up to date.

Best Regards.

Hi,

I am not aware about firmware issues which result in lower BLE output strength, so do not count on it being improved with a firmware upgrade. It could be that it is quite direction sensitive se perhaps rotating the IP22 charger around its axis might improve the situation.

I just started looking into reading the victron ble messages using arduino. The code looks interesting can you offer any suggestions or tips as I begin coding? I have been reading post on this and some have run into issues with the ever evolving victron ble data structure. Its a hobby project for my solar club and an excited to give it a try.

Bonjour Debbie,

I’m not exactly sure which device you are referring to, because I opened this discussion about the Orion XS, but then we continued the discussion about the IP22.

Since I’m not entirely sure what exactly you are looking for, here is some general information. Here is the setup I have used for my Victron devices on board the boat.

typedef struct {
  uint16_t vendorID;
  uint8_t beaconType;
  uint8_t unknownData1[3];
  uint8_t victronRecordType;
  uint16_t nonceDataCounter;
  uint8_t encryptKeyMatch;
  uint8_t victronEncryptedData[21];
  uint8_t nullPad;
} __attribute__((packed)) victronManufacturerData;

typedef struct {
  uint8_t deviceState;
  uint8_t errorCode;
  int16_t batteryVoltage;
  int16_t batteryCurrent;
  uint16_t todayYield;
  uint16_t inputPower;
  uint8_t outputCurrentLo;
  uint8_t outputCurrentHi;
  uint8_t unused[4];
} __attribute__((packed)) victronPanelData;

typedef struct {
  uint16_t bmvTTG;
  uint16_t bmvBat1Voltage;
  uint16_t bmvAlarmReason;
  uint16_t bmvBat2Voltage;
  uint8_t byte0;
  uint8_t byte1;
  uint8_t byte2;
  uint8_t byte3;
  uint32_t bmvData2;
} __attribute__((packed)) victronBMVData;

typedef struct {
  uint8_t deviceState;
  uint8_t errorCode;
  uint16_t outputVoltage;
  uint16_t outputCurrent;
  uint16_t inputVoltage;
  uint16_t inputCurrent;
  uint32_t offReason;
  uint16_t unused;
} __attribute__((packed)) victronOrionXSData;

This is an excerpt from the code in the file “acquisition_BT.cpp” which defines the structures used in my project.

The file address is: Victron-Energy-Monitor-WaveShare/SRC/acquisition_BT.cpp at main · FXVT/Victron-Energy-Monitor-WaveShare · GitHub

The project address is: GitHub - FXVT/Victron-Energy-Monitor-WaveShare: A Waveshare ESP32 S3 touch LCD 5B turned into a monitor screen for Victron devices (BMV712, Orion XS50, IP22, SmartSolar)

And the GitHub (repository): FXVT · GitHub

Best regards and happy new year.

I trying to read the BMV-712, I am new to coding and use platformio. Most of the example I have been studying are from arduino ide and have a hard time converting to the platformio and getting the .ini file loaded. Thank you for your reply and hope you have a great New Year.
